Anyone know what the output is for a factory 928 fuel sending unit in Ohms? I did a search and didn't see any older posts. I'm doing some planning on the project and I'm trying to determine if an aftermarket fuel gauge will be required (either GM-style 0/90 ohms or ATL 240/33Ohms) or if the factory cluster gauge can be used if I can have my new sender adjusted to the necessary range.

Dave did much work on the fuel sending unit r&r, perhaps on his extensive site.........brb.

Found it but it doesn't list resistances:

I got 5 Ohms when float is at the top of the unit and 70 Ohms when the float is at the bottom of the unit. Here's the post where I conducted the test when the unit was out of the '88.
